Abstract

The invention discloses a door closing device. The door closing device comprises a rectangular tubular shell, a slideway is formed in the center of the upper surface of the shell, a stop sliding blockis installed on the slideway, the outer end of the stop sliding block is connected with the closing end of a door, and an installing frame is fixed to the inner surface of the shell. An electromagnetis connected with one end of a metal buckle, the metal buckle is provided with an upper clamping portion, a releasing part is provided with a lower clamping portion, and the middle of the releasing part is connected with the installing frame through a second spring. A stop buckle is provided with a bottom plate, one end of the bottom plate extends to form a bearing surface in the vertical direction, the bearing surface is attached to the middle of the releasing part, a stop portion is further arranged at the upper end of the bottom plate, a clamping connection portion is arranged at the lowerend of the stop sliding block, and the stop portion and the clamping connection portion are clamped. A toggle switch is provided with an upper arm and a lower arm, a reset portion is further arrangedat the lower end of the stop portion, the lower arm is located at the lower end of the reset portion, and the upper arm is located on the outer side of the stop portion and stretches out of the slideway. The door closing device has the effects of simple structure, high response speed, stable operation and high safety.

Description

technical field [0001] The invention relates to the technical field of door closers, in particular to a door closer. Background technique [0002] The door closer is a device that can close the door to its initial position in time after the door is opened. It is generally used in various public or commercial occasions. It not only provides convenience for pedestrians to enter and exit, but also reduces the impact on people in the house. Interference, in addition, can also play a role in preventing building disasters such as fire. In order to achieve its effect, the lever assembly structure composed of various components will be installed in the door closer. However, the existing door closers are often troublesome to use and slow in response due to their complicated structure. And its manufacture is also more time-consuming and laborious, and the cost is also higher. Contents of the invention [0003] In order to solve one or more of the above problems, the present invent...
